Soak 1 cup cashews in 1 cup hot water for ~20 mins. Blend cashews and water until smooth. (Option to use 32 oz greek yogurt instead.)
Thinly slice 4 zucchini into long strips lengthwise (resembling lasagna noodles). This works best on a mandolin.
Place zucchini in oven and roast for 5-10 minutes or until lightly browned (remove halfway and carefully flip). Cool.
Finely dice ½ yellow onion & finely chop basil leaves.
In a large sauté pan over med-high heat, add the following: 1# ground turkey, chopped onion, 8 oz sliced mushrooms.
Cook for ~12 minutes, breaking apart turkey meat as you cook.
Stir in ~25 oz spaghetti sauce, remove from heat.
Separately, stir together the following for the “white layer”: Cashew cream (or 32 oz Greek yogurt), ~½ cup chopped basil leaves, optional 1 cup shredded parmesan.
Assemble lasagna by layering in a 9x13” pan: - ½ turkey-tomato sauce- zucchini “noodles” - ¾ white layer mix - zucchini “noodles” - remaining ½ tomato sauce Dot w/ remaining white layer mix and top w/ ½ cup parmesan (optional).
Cover w/ foil and bake lasagna for 50min-1hr or until bubbly/ heated through.
Allow to cool ~10 min.
